I purchased a 48' 1988 Hatteras FBSF in 2010. We use the boat as a part-time liveaboard. We have really enjoyed living on the boat so we are now thinking about moving up to something more comfortable. I know that the market for SportFish Yachts is slow. Ideally I would be interested in trading up. If anyone on the forums has any leads please let me know. Although I like the layout of the Betram 50 I dont really think it would add that much more room. The Betram 54 is roomier. I was also impressed with the Hatteras 55 closet space in the master as well as the accessibility to the outboard side of the engines. I would also welcome any suggestions. Thank you!
